8 Claims.

This invention relates to machines for converting a continuous web ofpaper or other sheet material into rolls of commercial size.

More particularly, the invention relates to converting machines of thisclass which are adapted to operate continuously, said machine providingfor transfer of the continuously moving web from each completed roll toa succeeding core or mandrel for initiation thereon of a new Windingoperation.

The principal object of this invention is to provide a relatively simpleand efficient machine of this characterf Another object of the inventionis to provide a simplified and efficient device for transferring the webfrom the completed roll tothe empty core or mandrel; as previously setforth.

The invention further resides in certain novel and advantageousmechanical and structural features hereinafter described and illustratedin the attached drawings, in which:

Figure 1 is a side elevational view of a machine made in accordance withour invention;

Fig. 2 is a fragmentary front elevational view of the machine;

Fi'g. 3 is a sectional elevational view showing details of the reelwhich constitutes a part of the transfer mechanism;

Fig. 4 is a diagrammatic sectional View illustrating the mode ofoperation of the transfer mechanism;

Fig. 5 is a fragmentary sectional elevational view illustrating a phaseof the operation of the transfer mechanism;

Figs. 6 and 'l are diagrammatic fragmentary sectional elevational viewsshowing still further phases of the transfer operation, and

Figs. 8 and 9 are detached views in perspec tive illustrating elementsof the mechanism shown particularly in Fig. 3.

With reference particularly to Fig. 4 of the drawings, the machinecomprises. a reel I which is intermittently rotated, as hereinafterdescribed. This reel has provision for supporting,

detachably, three mandrels 2 in uniformly spaced series around the axisof the reel shaft 3. The mandrels 2 function in the present instance tosupport cylindrical core elements 4, 5 and 6 respectively, upon which apaper web l is wound to produce the finished roll product. In. thepresent instance, the web l, which may be drawn from any suitablesource, travels continuously to the reel I, to be wound in successivelengths upon the cores supported on the respective mandrels. In Fig. 4,the core 4 has received its full complement of paper and carries a roll8 of the required paper content. The paper `web has been separated fromthis finished roll and is being wound upon the core 5, as illustrated at9. The core 6 occupies a position at the bottom of the reel in contactwith a felt-covered applicator roll II, the under side of this rollbeing immersed in water I2 in a suitable container I3. Means isprovided, as hereinafter described, for rotating the cores during theperiods when the web is being wound thereon and While the core is incontact with the moistening roll II. l

In Fig. 4 the reel I is for the moment stationary, and means isprovided, as hereinafter described, for temporarily locking the reel inthis and the corresponding positions to facilitate re-A moval of thefinished roll 8, and the insertion in the reel of the mandrel with a newcore for reception of the web in a subsequent Winding operation. Afterremoval of the finished roll and replacement thereof with a new core asdescribed,

the reel is advanced, as hereinafter set forth, in the' direction of thearrow, this movement of the reel eventually bringing the core 6 intocontact with the web 1 as the latter passes to the roll 9 still buildingon the core 5. During this movement of the reel, the web 1 continues toWind upon the roll 9. As the -core 6 is brought into engagement with theWeb, the transfer device, indicated generally by the reference numeralI4, descends upon the web intermediate the roll 9 and the core 6,thereby parting the web and tucking the free end thereof into the nipbetween the core 6 and a pinch roll I5 which is engaged with the core,as hereinafter described. This tucking ofthe end of the web around themoistened corel 6 initiates a new Winding operation, and thereby startsa new cycle of operations. In the present instance, the web 'I inpassing to the reel I is acted upon by one or more cutter blades I6 soas to slit the web into two or more longitudinal sections, the coresupon which the Winding operation takes place being composed ofcontiguous longitudinal sections for reception respectively of theseparate portions of the web.

Referring now to Figs. 1, 2 and 3, it Will be noted that the reel shaft3 is journaled in a bracket or' brackets I'I extending transversely fromthe fixed frame I8 of the machine. Secured to one end of the shaft is aratchet wheel I9 which is operatively engaged by a pawl 2 I on anoscillatory arm 22, this arm being pivotally mounted at 23 upon thebracket I'I. A spring 24 tends to draw the arm 22i away from the ratchetwheel I9, and the arm is advanced toward the wheel by action of a cam 25which is secured to a cam shaft 26 suitably journaled in the bottom ofthe frame I8. The cam 25 is engaged by a roller 21 at the lower end ofa. rod 28, this rod being slidably supported in guides 29 and 3| in theframe IB, and the rod carries a boss 32 which is connected through anadjustable link 33 with one end 34 of the arm 22. Vertical reciprocationof the rod 2,8 results in an oscillation about the pivot 23 of the arm22 and in intermittent rotation through the pawl 2| and ratchet I9 ofthe shaft 3. It will be noted by reference to Fig. 1 that the pawl 2| ismounted upon a block 35 slidably held in a guide slot 35 in the arm 22,and a spring 31 is connected to the block 35 and to the arm 22 to retainthe block with the pin 2| in the normal operative position with respectto the cam. The arrangement provides for outward movement of the pin inthe arm to an extent clearing the teeth of the ratchet I9, whichmovement is required during the retractive movements of the arm 22.

It will be noted by reference to Fig. 1 that the ratchet wheel I9 isformed in effect with three uniformly spaced teeth whereby eachoscillation of the arm 22 will cause the shaft 3 and the reel supportedthereon to move through an angle of 120. As previously set forth, meansis provided for locking the reel in the several positions to which it ismoved by the action of the pawl and ratchet. The locking means consistsof a bolt 33 mounted at the outer end of the arm 22 and projectinginwardly as shown in Fig. 2. Slidably supported on the bolt ls a collar39 which is normally retained in an advanced position bearing againstthe head of the boltby a spring 4| supported on the bolt. The collar 39is splined or is otherwise restrained from rotation about and upon thebolt, and has a radially projecting pin 42 which, as the arm 22 'movesto the left in Fig. 1, is adapted to engage an inclined vane 43 securedto a bifurcated tail element 44 on a pin 45, this pin being slidablysupported in the bracket I1, as shown in Fig. 3. The outer tapered headend 46 of the pin has a projecting key 41 which fits into a slot 48 inthe bracket I1 to thereby prevent the pin from rotating in the latter. Aspring 49 on the pin 45 tends to project the latter by reaction with thebracket |1 into a socket 5| in the end surface of the reel and when thepin is thus entered in the socket, the reel is locked in position withinits supporting bracket. By action of the pin 42 on the inclined vane 43,the pin 45 is retracted from the socket against the tension of thespring 49, so that the reel is then free to move under the action of thepawl and ratchet device previously described.

The arrangement is such that in the Working stroke of the lever 22, thatis to say, when the lever 22 is moving to the left as viewed in Fig. 1,the pin 42 will first act on the element 43 to retract the pin 45, afterwhich the continued movement of the lever 22 will engage the pawl 2|with the ratchet I9 to rotate the reel through an angle of 120, aspreviously set forth. After the initial movement of the reel, the pin 42clears the inner end of the element 43 and thereby permits the spring 49to advance the pin 45. Since this pin is now out of alignment with anyof the three uniformly spaced sockets in the end of the reel, the end ofthe pin comes into engagement with the end surface of the reel itselfand is not effective to immobilize the reel until the latter hasadvanced through an angle of 120, at which point the pin will again bebrought into registration with one of the sockets 5| and will enter thelatter under the pressure of the spring 49.

It is to be noted that the spring 4| permits a movement ofthe collar 39on the pin 38 sufficient to permit the pin 42 to clear the outer edge ofthe inclined member 43, when on the back stroke of the leverv 22 the pinwill engage the outer face of the said element. It is to be noted alsothat the working stroke of the lever 22 is suilcent to move the ratchetI9 through a full angle of and if the throw of the lever 22 is slightlyin excess of that required to afford this angular movement of theratchet, the lost motion between the lever and the ratchet is providedfor in the ability of the pawl to move outwardly in the slot 36.

The indexed position of the reel, that is, the position occupied by thereel when it is immobilized by means of the locking means describedabove, is shown in Fig. 4. In this position, the roll at the upperleft-hand corner of the reel is completed. The roll at the upperright-hand corner of the reel is in the process of buildup, and is inengagement with the pinch roll |5; and the core at the lower corner ofthe reel is in rotative contact with the felt-covered applicator rollWhile the reel is in this indexed and immobilized position, thecompleted roll is removed from the reel and is replaced by a bare corefor a subsequent winding operation.

The manner in which the mandrels 2 and cores 6 are held in the reel isbest illustrated in Figs. 2 and 3. The reel itself comprises the axisshaft 3, to the opposite end of which is secured a spider, 52 and 53respectively. The spider 52 has three axially extending bosses 54 whichare uniformly spaced around the shaft 3, so that each is separated fromthe other by an angle of 120. Journaled in each of the bosses onanti-friction bearings 55, see Fig. 2, is a spindle 56, and on eachspindle is a pulley 51, the said pulleys being aligned'in a plane atright angles to the axis of the shaft 3, as illustrated. The outer endof the spindle 56 is provided with a rectangular socket 58 whichreceives one correspondingly shaped lextremity 59 of the mandrel 2. Thespider 53 comprises three axially extended bosses 6| which are in axialalignment respectively with the bosses 54 of the spider 52. Journaled ineach of the bosses 6| upon anti-friction bearings 62 in a sleeve 63, andwithin this sleeve is slidably supported a spindle 64. The spindle 64issplined or keyed Y to the sleeve and carries a spring 65 which exertspressure tending to hold the spindle in an extended position, as shownin Fig. 3. This extended position of the spindle is controlled by a headange 66 on'the spindle which engages an end of the sleeve 63 to limitthe movement of the spindle with respect to the sleeve. The. spindle maybe retracted against the pressure of the spring 65, an axial space 61being provided at the outer end of the boss for that purpose. The innerend of each of the spindles is recessed at 68 for reception of theextremity 69 of the mandrel 2 whereby the mandrel is supported forrotation between the aligned bosses 6| and 54 of the spiders 53 and 52.

Preferably the mandrel 2 is `of the radially expansible and contractibletype, such for example as that disclosed in U. S. application SerialNumber 438,044, filed April 7, 1942. The cores 6 are inserted on themandrel when the latter is in a radially contracted condition, and themandrel is thereafter expanded so as to bind the mandrel frictionally inthe core. It will be noted that the completed roll may manual retractionof the spindles 64 in the bosses 6I.

As previously described, the completed rolls are removed from the reeland a new core inserted while the reel is immobilized in the positionshown in Fig. 4. Subsequent to the insertion of the bare core, the reelI is turned in the direction of the arrow, see Fig. 4, to bring the corewhich has received moisture from the roll I I into position to receivethe web 1, and to carry the newly inserted bare core downwardly intoengagement with the applicator roll I. It will be noted by referencetoFlgs. 1 and 2 that the pulleys 51 on the mandrel spindles 56 arearranged for engagement by a common drive belt 1 I. This belt issupported in part upon a driven pulley 12 journaled on a bracket 13 onthe frame I8y and on an'idler pulley 14 at the outer end of one of 'thebrackets I1. Between the pulleys 12 and 14 the belt is engaged by one ormore of the pulleys 51 and also by a weighted takeup pulley 15 which isjournaled on the end of an arm 16 pivlxotally attached at 11 to thebracket 13. The pulley 12 is driven by a belt 18 which operates on apulley 19 connected with the pulley 12, as shown in Fig. 2. It will beapparent that as the reel I is rotated, the pulleys 51 of the respectivemandrel spindles are brought successively into ,operative engagementwith the belt 1 I. The belt is engaged initially by the pulley 51 ofthat one of the mandrels which is moving from the applicator roll II, sothat the moistened and bare core carried by this mandrel is brought upto a rotational speed corresponding to or slightly in excess of thelinear speed of the web'1-before the core is brought into engagementwith the web. After transfer of the web is made to this core 6, theassociated mandrel and pulley 51 are maintained continuously inoperative engagement with the drive belt 1| until the winding operationis completed. The winding operation continues during the major part of.the rotational movement 'of the reel I, and until this movement hasbrought the succeeding bare core into contact with the web and the webhas been parted, as hereinafter described. Immediately after the partingof the web, which occurs approximately in the position of the reel shownin Fig. 7, the pulley 51, which is associated with the mandrel holdingthe completely wound core, passes out of engagement with the drive belt'1 I, as shown in Fig. l, so that be readily removed from the machine.

The web-parting and transfer device consists of a plurality of arms 8|secured to a rock shaft 82 suitably journaled at the upper end of theframe I8. Supported in the outer ends of the arms 8| is a rod 83 whichprovides a pivotal support for a plurality of depending arms 84, thelower ends of the arms 84 being connected by a cross bar 85, and to thisbar is rigidly secured a blade 86, the lower cutting edge 81 of which isserrated, as shown in Fig. 3. The blade 86 has a plurality of slots 88,and at the upper end of each of these slots and at one side of the bladea pair of bosses 89, in each of which pairs is supported a pivot pin 9|.Each of the pins 9| provides a pivotal tucking member 92, which as shownin Fig. 9 comprises a longitudinal blade 93 and an arm 94 more or lessof C-shape and having intermediate its support upon the blade for a' theshaft ends'an aperture 95 for reception of the pin 9|. The member 92 isthus supported-in the slot 88 of the blade in a manner such that blade93 and the upper transverse projecting end 96 of the arm 94 lie at oneface of the blade, as shown for example in Fig. 4.

One or more springs 91 arms 8| and 84 tend to draw the latter inwardlyto a position wherein lug 98 on the arm-84 engages the end of a setscrew 99 on the arm 8|, this engagement limiting the movement of the arm84 under action of the spring 91 and establishing the normal position ofthe blade 86'with respect tothe arm 8|. The tucking devices 92 normallyassume by gravity the relative position in the blade 86 shown in Fig. 4,but are free to move with respect to the blade, as hereinafterdescribed, in the tucking operation. Similarly the arm 84 may move tothe left; as viewed in Fig. 4, about the pivot rod 83 on the outer endof the arms 8|.

The arms 8|, and the transfer device I4 as a whole, are adapted to beheld in an elevated position through the medium of a latch or detent |8Iat the top of the frame I8 which interlocks with a tooth |82 on a disk|83 secured to the shaft 82. The elevated position determined by theaction of thislatching means is illustrated in solid lines in Fig. \l..The arms 8| are adapted to be elevated to this position through themedium of a rod |84 which is slidably mounted in the frame I8 and whichcarries at its lower end a roller |85 for engagement with a c am |86secured to the shaft 26 which also carries the cam 25 previouslydescribed. The rod |84 has a lug |81 which is connected to the armsthrough a link |88, this link being attached at its upper end to an arm|89 extending from the shaft 82. The cam |86 acts to elevate the arms 8|to a position higher than the aforesaid locked position, as indicated inbroken lines in Fig. l, but downward movement of the arms after suchelevation is limited by the latch I8I, which, as previously described,holds the arms in an elevated position.

The latch |8I is operatively connected with a solenoid III which, whenenergized, acts to retract the latch to thereby release the disk |83,82, and the associated parts so as to permit the arms 8| and the partsconnected thereto to drop downwardly, this release being timed to takeplace when the parts are approximately in the position shown in Fig. 6,in which position a bare core has been broughtr into con tact with theweb. Downward movement of the arms 8| is aided by a. spring II5, one endof which is secured to the frame and the other end to an arm |I6 on theshaft 82; and the downward movement of the arms 8| is positively lim*-ited by a stop member I I2 on the frame 'i8 which carries a resilientpad I|3 for engagementbythe outer end of an arm I I4 on the shaft 82.

The mode of operation of the web-parting and tucking means is bestillustrated in Figs. 4 to 7,

inclusive. The transfer device I4 is released by energization of thesolenoid III, as hereinafter described, when it occupies the positionapproximately asv illustrated in broken lines in Fig. 7, the reel thenbeing approximately in the position shown and the web extendinguninterruptedly to the roll 8 also as indicated 'in broken lines.Downward movement.

sharp engagement with the web which is immedie ately parted, the freeend of the web then being carried by the continued downward movementsecured between the A of the transfer device brings the cutting edge 81of the blade 86 into of the blade and of the associated tucking devices92 downwardly and around the empty core 6, which is now in engagementwith the web, as illustrated in Fig. 7. The projecting portions 96 ofthe tucking devices 92 rst engage the upper side of the rotating core,and as a result of this initial engagement, the blades 93 of the tuckingdevices are brought sharply up underneath the core 6, see Fig. 7, andclose into the nip of the core 6 with the pinch roll H5. This carriesthe free end of the web around the core and upwardly to be caught underthe web and in the said nip so as to initiate the new winding operationupon the core.

The pinch roll I is supported on a pair of arms HI secured to a shaft H8suitably journaled in the frame I8, and theshaft H8 has an arm H9 whichis connected to a spring |2| in such manner that the spring exerts apressure tending to turn the shaft H8 in a counterclockwise direction,as viewed in Fig. 1. Thus the pinch roll I5 is held in pressureengagement with the empty core 6 as the latter is moved into engagementwith the web and remains in pressure engagement with the roll during themajor portion of the winding operation. In the subsequent movement ofthe reel, the partially wound roll is withdrawn from the pinch roll I5,as illustrated in Fig. 5, and the roll is then supported in engagementwith the web and 'in the position shown in Fig. 5 by means of a stoplink |22 associated with the spring I2 I.

After completion of the transfer, the cam |06 progressively elevates thearms 8| of the transfer device, as previously described, until the armsreach their maximum height, this corresponding to the point |23 on thecam |06, as shown in Fig. 2. This extreme position of elevation is shownin Fig. 6, and it will be noted that in this position the lower edge ofthe blade 86 is sufficiently high to afford clearance for the roll 8when the reel I is turned as described. The cam |06 supports 'the arm inthis extreme position of elevation over a period of time during whichthe reel is making the major part of one of its cyclic movements anduntil the roller |05 reaches the point on the cam |06 ,indicated at |24.Continued movement of the cam then permits the transfer dev'ice to movedownwardly to a position shown in broken lines in Fig. 7 in which thelower edge of the blade 86 is relatively close to the web then passingto the roll 8, it being noted that in this position the pulley 51associated with the roll 8 is still in engagement with the belt 'I I.The roller |85 is now at the point |25 of the cam |06, and a as the camrotates the roller is entirely released to permit the transfer device todrop by gravity aided by the action of the spring H5, with the resultdescribed above.

The cam shaft 26 is driven through a reduction gear unit |26 by a belt|2'I which extends to a pulley |28 on a shaft |29. This shaft issuitably connected to a source of power, which source is also connected,by means not shown, with the belt 18. The shaft 26, in addition to thecams 25 and |06, carries a pulley |3| which is connected through a belt|32 and twist pulleys |33 with a pulley |34 on the shaft |35 of the rollI 'f It is apparent that the several operating parts of the machine maybe closely synchronized to afford the operative results described above.
